if homosexuality is a sin, why isn't abstinence?Are you talking about the assumption that homosexuality is a sin? Because I was under the impression that within the scope of Christianity, the sinfulness of any act and the reasons therewith were objectively verifiable via the Bible.

if homosexuality is a sin, why isn't abstinence?How is a homosexual act using the power to procreate? If it does not have the power to procreate, how is it using said power? It seems to fall under the same category as sexual acts other than intercourse. And what I am saying is that to say homosexuality is wrong on the grounds that it does not result in procreation is contradictory--because it would imply that anything that doesn't result in procreation is a sin. What sets homosexuality apart from any other act that does not result in procreation? And I challenge you to find fallacy in such a question.

if homosexuality is a sin, why isn't abstinence?So that brings me to the question, what defines "sex"? Obviously the Bible has never strictly defined what sex is, so it seems that many people have made their own ad hoc assumptions about it. But, without getting into gritty details, my understanding is that sexual intercourse as the Bible defines it is between a man and a woman. Therefore how does homosexuality fall under the category of sex, such that doing it out of wedlock is adultery? And how can you compare it to sex between a man and a woman?
